A detached screw may lodge between the frame and stem, interfering with steering and increasing the risk of a crash or injury.

Additional letters will be sent once the final remedy is available, anticipated in Winter 2026. Owners may contact Honda's customer service at 1-866-784-1870. Honda's number for this recall is KUO. This recall expands previous NHTSA recall number 26V146. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning August 4, 2026.
POWER TRAIN:MANUAL TRANSMISSION
